(4,?) is on the line below. find the other half of the coordinate. y=2/7x+3

Savatey [412]

Since we have (4,?) we know x=4. Substitute this into the equation and solve for y.

y= 2/7*4+3

y= 2/7*4/1+3

y= 8/7+3

y= 8/7 + 3/1

y= 16/14 + 42/14

y= 58/14 or 4.14

Answer:

Value of x1 = 10 and x2 = -3

Step-by-step explanation:

$when \: we \: multiply \: the \: above \: matrices \\ we \: get \\ 2x1 + 6x2 = 2 \: \: \: \: and \\ 0x1 + 1x2 = - 3 \\ then \: \: x2 = - 3 \\ on \: substituting \: x2 = - 3 \:\\ in \: first \: equation \: \\ 2x1 + 6( - 3) = 2 \\ 2x1 - 18 = 2 \\ 2x1 = 20 \\ x1 = \frac{20}{2} \\ x1 = 10$
