If the bench costs x dollars we have the equation
x + x - 62 = 688
2x = 750
x = $375
The bench cost $375
<h3>Answer:</h3>
x=5, y=2
<h3>Explanation:</h3>
The second equation gives an expression for x that can be substituted into the first equation.
... (y+3) +y = 7 . . . . . .substitute y+3 for x
... 2y + 3 = 7 . . . . . . . colect terms
... 2y = 4 . . . . . . . . . . subtract 3 from both sides
... y = 2 . . . . . . . . . . . . divide both sides by 2
Using the expression for x, we can find its value.
... x = y + 3
... x = 2 + 3 . . . . . . . . . substitute for y
... x = 5
The solution is (x, y) = (5, 2).
Answer:
3x times 4
Step-by-step explanation:
Answer:
2x + y = 4
4x + 2y = 12
Step-by-step explanation:
Equations 2x + y = 4 & 4x + 2y = 12 haven't the same solution.
