Answer:
(x, y) = ( -4 , 4)
Step-by-step explanation:
STep 1: substitute the given value of x into the equation -7 x - 6y = 4 which will be -7 (-3 y + 8) - 6 y = 4
STEP 2: solve the equation for y so basically -7 (-3 y + 8) - 6 y will be y = 4
STEP 3:substitute the given value of x into the equation so y = 4 would be
x = -3 x 4 + 8
STEP 4: solve the equation for x. -3 x 4 + 8 which you'd end up with x = -4
Answer:
8
Step-by-step explanation:
So for me, how I would do it is move the variables and numbers to one side. So we have the equation 3x-3=2/5x+7. So you would subtract 2/5x to the left side and add 3 to the right side. The equation will then turn out to be 3x-2/5x=7+3. Much more easier right? So just simplify both side, and you will get 13/5x=10. In order to isolate x, you have to divide 13/5 in both side, leaving x= 3 11/13 or 50/13. You can always plug the answer back in to double check :)
