Question

Solve each problem:

a. 4x=-28 x=
b. x-(-6)=-2 x=
c. -x 4=-9 x=
d.-3x 7=1 x=
e. 25x (-11)=-86 x=

A. x = -7
B. x = 7
C. x = 4
D. x = -4

Answer 1

To solve each problem, use the given equations and perform the necessary operations to find the value of x.

Step-by-step explanation:

To solve the given equations:

1. a) 4x = -28, x = -28/4, x = -7
2. b) x - (-6) = -2, x + 6 = -2, x = -2 - 6, x = -8
3. c) -x/4 = -9, -x = -9 * 4, x = -36, x = 36
4. d) -3x/7 = 1, -3x = 7, x = 7/-3, x = -7/3
5. e) 25x * (-11) = -86, -275x = -86, x = -86/(-275), x = 0.313
