Answer:
x = 28
Step-by-step explanation:
The ratios of corresponding sides are equal, that is
= 
( cross- multiply )
8(x - 7) = 168 ( divide both sides by 8 )
x - 7 = 21 ( add 7 to both sides )
x = 28
G = 18.5. Add 1.5 to both sides, and calculate

Answer:
x = -5.975
Step-by-step explanation:
distribute first by multiplying 2/5 by 'x' and then by 9/10 to get:
2/5x - 18/50 = -2 3/4
next, change -2 3/4 into an improper fraction to get:
2/5x - 18/50 = -11/4
now add 18/50 to -18/50 and to -11/4 using a common denominator of 100
2/5x = -275/100 + 36/100
2/5x = -239/100
multiply each side by 5/2 to isolate 'x':
x = -239/100 · 5/2
x = -1195/200
now simplify:
x = -5.975
