No 1: Equation: 3x + 5 = 17
3x = 17 - 5
3x = 12
x =
x=4
2(2y - 3) = 10
Distribute the 2 on the left side:
4y - 6 = 10
Add 6 to both sides to isolate the variable:
4y = 10 + 6
4y = 16
Divide both sides by 4 to find the value of y:
y =
y=4
3. Equation: 5(a + 2) - 3(a - 1) = 16
Working Out:
Distribute the 5 and -3 on the left side:
5a + 10 - 3a + 3 = 16
Combine like terms:
2a + 13 = 16
Subtract 13 from both sides to isolate the variable:
2a = 16 - 13
2a = 3
Divide both sides by 2 to find the value of a:
a=3/2
a = 1.5
4. Equation: 2(x + 3) = 3x - 4
Working Out:
Distribute the 2 on the left side:
2x + 6 = 3x - 4
Subtract 2x from both sides to isolate the variable:
3x = 17 - 5
3x = 12
x =
x=4
2(2y - 3) = 10
Distribute the 2 on the left side:
4y - 6 = 10
Add 6 to both sides to isolate the variable:
4y = 10 + 6
4y = 16
Divide both sides by 4 to find the value of y:
y =
y=4
3. Equation: 5(a + 2) - 3(a - 1) = 16
Working Out:
Distribute the 5 and -3 on the left side:
5a + 10 - 3a + 3 = 16
Combine like terms:
2a + 13 = 16
Subtract 13 from both sides to isolate the variable:
2a = 16 - 13
2a = 3
Divide both sides by 2 to find the value of a:
a=3/2
a = 1.5
4. Equation: 2(x + 3) = 3x - 4
Working Out:
Distribute the 2 on the left side:
2x + 6 = 3x - 4
Subtract 2x from both sides to isolate the variable:
