Answer:The solution of an equation with two variables, x and y, is an ordered pair (x, y) that produces a true statement when the values x and y are substituted into the equation.
The answer is x = -3.8.
Step 1: add 7+3 (2x+10=-3x=9)
Step 2: add 3 to each side of the equation (5x+10=-9)
Step 3: subtract 10 from each side of the equation (5x=-19)
Step 4: divide by 5 on each side of the equation (x=-3.8)
