Multiply 88 by 7, then multiply 88 by 3 and move the decimal point one to the left. Then add those two numbers. That's your answer.
You cross multiply
a c
- = -
b d
if ad equals bc, then the fractions are equivalent
180-106=74
X is congruent to 2y
x=74
74/2= 37
y=37
(4z+6) is congruent to 106
106-6= 100
100/4 = 25
z=25
