Step-by-step explanation:
LHS = 5x+y =5(1)+2= 5+2= 7
RHS = 7
since LHS= RHS
LHS = 7x-2y =7(1)-2(2)=7-4=3
RHS = 3
since LHS=RHS

Step-by-step explanation:
Answer:
6 1/3
Step-by-step explanation:
3 times what equals 19 can be in the form of an equation as shown below. It shows that the value we are finding for is unknown, therefore it is a variable. A variable is the unknown value in an equation.
Equation: 3x = 19
With the equation in hand, we can now solve the problem easily.
3x = 19
Carry the 3 to the 19(Carry over the like terms across leaving the variable or the unknown)
x = 19÷3
x = 6.33333 or 6 1/3
To check if the answer was correct:
3 × 6 1/3 = 19
You regain the answer <em>19</em>
