Please help me to Solve the simultaneous equations

x = 0.5 or 1/2

y = 4

Step-by-step explanation:

to solve this simultaneous equation , using the substitution method we are going to say that

let

2x + 3y = 13 equation 1

4x - y = -2 equation 2

from equation 2

4x - y = -2 equation 2

collect the like terms

4x+2 = y

y = 4x + 2 equation 3

put the value of y into equation 1

2x + 3y = 13 equation 1

2x + 3(4x+2) = 13

2x + 12x + 6 = 13

14x = 13 -6

14x = 7

divide both sides by the coefficient of x

we have

14x/14 = 7/14

x = 1/2 or 0.5

substitute for x = 1/2 in equation 3

y = 4x + 2 equation 3

y = 4(0.5) + 2

y =2+2

y = 4

i can't solve unless i know what the line is

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
