7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
How do you solve 2 bracket 7x plus y bracket-3bracket5x-2ybracket?
Solve the brackets, starting from the innermost and working outwards: 2(7x+y(-3(5x-2y))) multiply by -3: 2(7x+y(-15x+6y)) multiply by y: 2(7x - 15xy+6y2) multiply by 2: 14x - 30xy + 12y2 I suspect, though, that there is something missing before the -3.
How do you solve -21-4x equals 9-7x?
-21-4x=9-7x 7x-4x=9+21 3x=30 x=30 / 3 therefore x=10
