Solve 3x plus 2y equals 0 and -9x plus y equals 42 using substitution method?
3x+2y = 0 -9x+y = 42 => y = 42+9x Substitute the bottom rearranged equation into the top equation: 3x+2(42+9x) = 0 3x+82+18x = 0 21x = -84 Divide both sides by 21 to find the value of x: x = -4 Substitute the value of x into the original equations to find the value of y: So: x = -4 and y = 6
15 plus 3x 42 then x?
If 15 + 3x = 42, then x = 9
