3x plus 4y equals 90 4x-3y equals -5?
This is a simultaneous equation question. 4(3x+4y = 90) 3(4x-3y = -5) Multiply the top equation by 4 and the bottom equation by 3 then subtract the bottom equation from the top equation remembering that in maths a minus from a minus is equal to a plus. 12x+16y = 360 12x-9y = -15 And when subtracted: 0+25y = 375 Divide both sides of the equation by 25 to find the value of y: y = 15 Substitute 15 for y into the original equation to find the value of x: Solution: x = 10 and y = 15
