Explanation:
"collect like terms on left side of equation"
x-7=10
"add 7 to both sides"
xcancel(-7)cancel(+7)=10+7
x=17
color(blue)"As a check" Substitute thus value into the left side of the equation and if equal to the right side then it is the solution.
(-2xx17)-7+(3xx17)=-34-7+51=10
x=17" is the solution"
