Question

EXE
olve the following equa
1. 3x = 2x + 18
1. 4z + 3 = 6 + 2z
4
. x=
5
(x + 10)​

Answer 1

Step-by-step explanation:

3x = 2x + 18

3x - 2x = 18

x = 18

Answer 2

Correct Question:

Solve the following equations:

a) 3x = 2x+18

b) 4z+3 = 6+2z

c) x = 5(x+10)

Answers:

a) 3x = 2x+18

3x-2x = 18

x = 18

b) 4z+3 = 6+2z

4z-2z = 6-3

2z = 3

$z = \frac{3}{2}$

c) x = 5(x+10)

x = 5x+50

-50 = 5x-x

-50 = 4x

$\frac{ - 50}{4} = x$

$\frac{ - 25}{2} = x$
