Write two equations in standard form that are equivalent to the given equation.
1.5x+10y=15
2.-9x-12y=6
3.-2x+4y=-5

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

Four quarts of a latex enamel paint will cover about 200 square feet of wall surface. how many quarts are needed to cover 98 square feet of kitchen wall and 52 square feet of bathroom wall

Solve this system of equations: y=x2-3x + 12 y=-2x+14 4. substitute the values of x, -1 and 2, into either origina equation to solve for the values of y. what are the solutions of the system of equations?
