Step-by-step explanation:
4x+10y=100
2x+3y=25
by multiplying:
8x+20y-200=0
8x+12y-100=0
(- ) (-) (+)
8y-100=0
y=100/8
y=25/2
to find x -
4x+10y=100
4x+10*25/2=100
4x=100-125
x=-25/4
Answer:
[tex]The Elimination Method
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation1 or Equation 2 above and solve for x.
