Solve the system of equations.

Alenkasestr [34]

Step-by-step explanation:

<u>Step 1: Substitute x from the second equation into the second one</u>

$2x - 9y = 14$

$2(-6y + 7) - 9y = 14$

$(2 * -6y) + (2 * 7) - 9y = 14$

$-12y + 14 - 9y = 14$

$-21y +14 - 14 = 14 - 14$

$-21y/-21 = 0 / -21$

$y = 0$

<u>Step 2: Substitute y into the second equation</u>

$x = -6y + 7$

$x = -6(0) + 7$

$x = 0 + 7$

$x = 7$

Answer: $x = 7, y = 0$

Solve for x: -2(x + 3) = -4x + 20

Phantasy [73]

Answer:

Step-by-step explanation:

Lets start with 13

-2(13 + 3) = -4(13) + 20

-32 = -52 + 20

-32 = -32

x = 1 basically

now 19

-2(19 + 3) = -4(19) +20

-44 = -76 + 20

-44 = -56

so divide those

-2(31 + 3) = -4(31) + 20

-68 = -124 + 20

-68 = -104

divide them

-2(37 + 3) = -4(37) + 20

-80 = -148 + 20

-80 = -128

Jack spends 15% on sweets each week and 35% on magazines. His total spendings(15%+35%=50%)equals 50%.Savings is 100% - 50%= 50%.So, if jack gets $100 each week, he spends $15 on sweets, $35 on magazines, and $50 goes towards savings. Hope this helps!
