Because "y" is + in <span>2x+y=7, let's subtract 2x from both sides and end up with an expression for y: y = 7 - 2x. Substituting this into 5x - 3y = 23,
5x - 3(7 - 2x) = 23. Multiply out -3(7 - 2x):
5x - 21 + 6x = 23. Combining 5x and 6x, 11x - 21 = 23, or 11x = 44.
Thus, x = 4. Since y = 7 - 2x, subst. x = 4 results in the value of y:
y = 7 - 2(4) = 7 - 8 = -1.
The solution is (4,-1).</span>
Calculate the interest for a yearinterest/year = percentage × deposit
interest/year = 7.5% × 300
interest/year =

interest/year =

interest/year = 22.5
She will get $22.5 in a year
Calculate interest in 5 yearsinterest in 5 years = interest per year × 5
interest in 5 years = 22.5 × 5
interest in 5 years = 112.5
She will get $112.50 in 5 years
