What is 50-{3(4.25)+2(2)+7= I have been getting different answers and can't figure it out.
I don't know how to change the thing out of college

t

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

there still no table

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
