Steps Problem Solution

1

Simplify the equation

\$ -7(x-a)=14 \$

2

Given equation

\$ -7(x-a)=14 \$

3

After eleminating the brackets

\$ -7x+7a=14 \$

4

Adding "-7a" on both sides of the equation

\$ -7x+7a-7a=14-7a \$

5

After cancellation we get

\$ -7x=14-7a \$

6

Dividing on both sides by "7" we get

\$ (-7x)/7=(14-7a)/7 \$

7

After simplification we get

\$ (-7x)/7=(14/7)+(-7a/7) \$

8

After cancellation we get

\$ -x=2-a \$

9

Multipling "-1" on both sides of the equation

\$ (-1)×(-x)=(-1)×(2-a) \$

10

After Multiplication we get

\$ x=(-1)×(2)+(-1)×(-a) \$

11

Hence the solution of the given equation is

\$ x=-2+a \$
