1) The sum of a number, x, and another number, y, is 62. yis 16 less than x. Find xand y.
x + y = 62 x =
y = x- 16
y =
2) The sum of a number, x, and another number, y, is 138. yis 36 more than x. Find xand y.
x=
y=
Generally we ask the member to show what they have been able to do, even if it is very little. Please do this from now on.
Now. Both problems are solved the same way. For the first one we have
$\displaystyle x + y = 62$
$\displaystyle y = x - 16$
Two equations, two unknowns. We know that y = x - 16, so plug that value of y into the first equation, then solve for x.
Can you finish from here?
