2x-7y=0
2x=7y
x=7/2y
Substitute that into x-6y=-5
7/2y-6y=-5
-2.5y=-5
y=2
x=7/2 x 2 = 7
x=7, y=2
Hope this helps.

Answer:
936mm^2
Step-by-step explanation:
Surface area of cuboid 20 mm 8mm 11mm
Surface area of the cuboid=2(20×8+8×11+11×20)
=2(160+88+×220)
=2(468)
=936mm^2
So the answer is936mm^2
4/10
= 0.4
= 40% so that means 0.4 is the decimal
Just multiply the two together. .68*425 =289
