2x + y = 4 \\ 3x - y =  - 14

Lets add 2 equations

5x =  - 10 \\ x =  - 2

Now we need to put x into any equation

2 \times ( - 2) + y = 4 \\  - 4 + y = 4 \\ y = 8

Answer: (-2; 8)

How do I solve this?<br> I have the answer but what is the step-by-step explanation.
velikii [3]

-7 = 1 + 2/3n

Subtract 1 from both sides:

-8 = 2/3n

Multiply both sides by 3:

-24 = 2n

Divide both sides by 2:

N= -12

Find the ordered pairs for the x- and y-intercepts of the equation 2x − 6y = 24 and select the appropriate option below. (5 poin
Blizzard [7]

Answer: C

Step-by-step explanation:

The x-intercept is found when y=0, and the y-intercept is found when x=0.  If y=0, then we have:

2x=24

x=12

Therefore, the x-intercept is 12, so the full coordinates are (12, 0).  Note that the only option with this x-intercept is C, so C is the correct answer.

You can find the y-intercept similarly.  If x is zero, then:

-6y=24

y=-4

Therefore, (0, -4) is the y-intercept.

What is x3/4 equivalent to
zhenek [66]

Answer:

3/4 = 6/8 = 9/12 = 12/16

= 15/20 = 18/24 = 21/28 = 24/32

= 27/36 = 30/40 = 33/44 = 36/48

= 39/52 = 42/56 = 45/60 = 48/64

= 51/68 = 54/72 = 57/76 = 60/80

= 63/84 = 66/88 = 69/92 = 72/96

= 75/100 = 78/104 = 81/108 = 84/112

= 87/116 = 90/120 = 93/124 = 96/128

= 99/132 = 102/136 = 105/140 = 108/144

= 111/148 = 114/152 = 117/156 = 120/160

= 123/164 = 126/168 = 129/172 = 132/176

= 135/180 = 138/184 = 141/188 = 144/192

= 147/196 = 150/200 = 153/204 = 156/208

= 159/212 = 162/216 = 165/220 = 168/224

= 171/228 = 174/232 = 177/236 = 180/240

= 183/244 = 186/248 = 189/252 = 192/256

= 195/260 = 198/264 = 201/268 = 204/272

= 207/276 = 210/280 = 213/284 = 216/288

= 219/292 = 222/296 = 225/300 = 228/304

= 231/308 = 234/312 = 237/316 = 240/320

= 243/324 = 246/328 = 249/332 = 252/336

= 255/340 = 258/344 = 261/348 = 264/352

= 267/356 = 270/360 = 273/364 = 276/368

= 279/372 = 282/376 = 285/380 = 288/384

= 291/388 = 294/392 = 297/396 = 300/400
