Math Problem Statement

Solve the following linear equalities in one variable: a) 3x = -24 b) 7z + 56 = -z c) 14x + 3 = 45

Solution

The image contains three linear equations to solve, each involving a single variable. Here are the solutions for each equation:

1. Solve the following linear equations:

a) 3x=243x = -24

Solution: Divide both sides by 3 to isolate xx: x=243x = \frac{-24}{3} x=8x = -8

b) 7z+56=z7z + 56 = -z

Solution: First, move all terms involving zz to one side by adding zz to both sides: 7z+z+56=07z + z + 56 = 0 8z+56=08z + 56 = 0 Subtract 56 from both sides: 8z=568z = -56 Divide by 8: z=568z = \frac{-56}{8} z=7z = -7

c) 14x+3=4514x + 3 = 45

Solution: Subtract 3 from both sides: 14x=45314x = 45 - 3 14x=4214x = 42 Divide by 14: x=4214x = \frac{42}{14} x=3x = 3

Final Answers:

a) x=8x = -8
b) z=7z = -7
c) x=3x = 3
