Best Answer

Someone's homework? This is a pair of simultaneous equations: 1) 3x - 4y = 10 2) y = x - 3 Substituting for y in equation 1: 3x - 4(x-3) = 10 3x - 4x + 12 = 10 -x + 2 = 0 -x = -2 x = 2 substitute into equation 2: y = 2 - 3 y = -1

What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?

3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3

How do you solve linear equation 2x plus 3xy-4y equals 10?

2x+3xy-4y=10to solve for yyour objective will be to get y by itself on one side of the equal signyou first subtract 2x to get the terms with y variables on one side3xy-4y=10-2xthen undistribute the y from the two terms to get one yy(3x-4)=10-2xnow divide 3x-4y=(10-2x)/(3x-4)theres your answer

Can you show me how to solve graphically 3x plus 4y equals 5 and x-2Y equals 5?

3x + 4y = 5x - 2y = 5leads to:x = 5 + 2ySo:3(5 + 2y) + 4y = 515 + 10y = 510y= -10y=-1and therefore if y = -1 then x = 3.

Solve this equation using subtitution x equals 4y and 3x-2y equals 20?

3x - 2y = 20 Substitute x = 4y into this equation: 3(4y) - 2y = 20 ie 12y - 2y = 20 10y = 20 so that y = 2 and then x = 4y gives x = 2*4 = 8
