The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30?

If so then the solution is:

-10+5y= -30

5y = -30+10

5y = -20

y = -4

Substitute the value of y into the equation -6x+3y = -18:

Answer: x = 1 and y = -4

Solve this equation using substitution 5x plus y equals 5 and 3x plus 2y equals 3?

From first equation: y = 5 - 5xSubstitute for y in second equation: 3x + 10 - 10x = 3ie -7x = -7ie x = 1 and y = 0

What is y equals 4x-10 and y equals 5-x solve using substitution?

By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2

Y equals 4x minus 8 and y equals 2x plus 10 sole using system of equations using substitution?

y = 4x-8 and y = 2x+10 4x-8 = 2x+10 4x-2x = 10+8 2x = 18 x = 9 Substitute the value of x into the original equations to find the value of y: Therefore: x = 9 and y = 28

-4 plus 10 equals?

-4 plus 10 equals 6.

If y-3 equals 7 and x plus 3y equals 6 then x equals?

This can be solved a number of ways. In thi case I prefer substitution. y-3=7 simplifies to y=10. Substitute 10 in for y so you get x+3(10)=6. Simplify this and you get x=-24
