Answer:
Let's solve for x.
4x+2y=345x−6y
Step 1: Add -345x to both sides.
4x+2y+−345x=345x−6y+−345x
−341x+2y=−6y
Step 2: Add -2y to both sides.
−341x+2y+−2y=−6y+−2y
−341x=−8y
Step 3: Divide both sides by -341.
−341x
−341
=
−8y
−341
x=

Answer:
Step-by-step explanation:
4x+2y=34;5x−6y=34
Step: Solve 4x+2y=34 for x:
4x+2y=34
4x+2y+−2y=34+−2y(Add -2y to both sides)
4x=−2y+34
4x 4 =−2y+34 4
(Divide both sides by 4)
x=−1/2y+17/2
Step: Substitute
−1/2y+17/2
solve for x in 5x−6y=34:
5x−6y=34
5(−1/2y+17/2)−6y=34
−17/2y+85/2=34(Simplify both sides of the equation)
−17/2y+85/2+−85/2=34+−85/2
(Add (-85)/2 to both sides)
−17/2
y=−17/2/−17/2y−17/2=−17/2/−17/2
(Divide both sides by (-17)/2)
y=1
Step: Substitute 1 for y in
x=−1//2y+17/2:
x=−1/2y+17/2
x=−1/2(1)+17/2
x=8 (Simplify both sides of the equation)
