I would use the process of elimination. Divide 13 from both sides
2x+7y=-57 y=-7 then plug in y to an equation
-6x-8y=80 2x+7(-7)=-57 multiple
multiple the first equation by 3 2x-49=-57 add 49 to both sides
6x+21y=-171 2x=-8 divide two from both sides
-6x-8y=80 x=-4
combine like terms So your things would be x=-4 and y=-7
13y=-91 And itd make the solution (-4,-7).
6xy+32
You multiply 8x by each number and get
24/4xy+32 You can simplify the 24/4 to get six. so your answer is
6xy+32
3/4*1/4= 3/16 or 0.1875 (you times 3 by 1 and 4 by 4)
3/4*8= 6
first bracket = 3/16+ 6
1/2+2= 2 1/2 or 2.5
second bracket = -2.5
-3/8*4= -1.5
-3/8*x= -3/8x or -0.375x
third bracket= -0.375x
so
(0.1875+6) - (2.5) - (0.375x) - (0.25x)
collect like terms
6.2 - 2.5 = 3.7
0.375x - 0.25x = 0.125x
3.7-0.125x is your answer in decimal form
(3/16+6/1) - (2 1/2) - (3/8x-1/4x)
(6 3/16 - 2 1/2 )
(3 11/16)
3/8x-1/4x= 1/8x
final answer = 3 11/16 - 1/8x
