Answer:

He could use y+3x=-4

Step-by-step explanation:

When we subtract 3x on both sides, we get y=-4-3x, which means we just solved a variable and can substitute into the other equation 2x-3y=-21

Answer:

y = 2

Step-by-step explanation:

Given

$\frac{2y-1}{15}$ = $\frac{y}{10}$ ( cross- multiply )

10(2y - 1) = 15y ← distribute left side

20y - 10 = 15y ( subtract 15y from both sides )

5y - 10 = 0 ( add 10 to both sides )

5y = 10 ( divide both sides by 5 )

y = 2
