1. A. Solve for the indicated variable.1. 2X = 642. 3y = 93. 5f= 1254. 10x = 10,0005. 88a=64​

Answer:

Divide everything by the coefficient of the variable to isolate the variable:

1. 2x=64

[tex]{\large \frac{2x}{2} = \frac{64}{2}}[/tex]

x=32

2. 3y=9

[tex]{\large \frac{3y}{3} = \frac{9}{3}}[/tex]

y = 3

The rest you can solve. Just follow what I did.

#5 just reduce it to lowest term. Divisible by 8 because 64 and 88 are multiples of 8.

64÷8=8

88÷8=11
