Question

Find the value of x and y from the following equations: 1] 4x+10y=100 2] 2x+3y=25 Use either Elimination or Substituting method

Answer 1

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 2

Answer:

$The Elimination Method</p><p></p><p>Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...</p><p></p><p>Step 2: Subtract the second equation from the first.</p><p></p><p>Step 3: Solve this new equation for y.</p><p></p><p>Step 4: Substitute y = 2 into either Equation1 or Equation 2 above and solve for x.</p><p></p><p>$
