Question

5. 32 = 4(x + 9)

6. 2(x-3) = -4.
7. Z(X + 6) = 77
8
8.-9(x - 8) = 27
9. 5(2c + 7) = 75
10. 6(3d +5) = 84




i might as well do this in one, this is due today and i don’t get it, someone help with explaining for the equations

Answer 1

5) 32 = 4(x + 9)

4(x + 9) = 32
[4(x + 9)]/4 = 32/4
x + 9 = 8
x = 8 - 9
x = -1

6) 2(x - 3) = -4

2(x - 3) = -4
2x - 6 = -4
2x - 6 + 6 = -4 + 6
2x/2 = 2/2
x = 1

7) Z(X + 6) = 77

[Z(X + 6)]/Z = 77/Z
X + 6 = 77/Z
X + 6 - 6 = 77/Z - 6
X = 77/Z - 6
